This Technical Report discusses issues related to emergency calls from an enterprise user to a safety answering point (SAP) using the Session Initiation Protocol (SIP) within a Next Generation Corporate Network (NGCN). A SAP can be either a public safety answering point (PSAP) or a private emergency answering point (PEAP). This Technical Report uses terminology and concepts developed in ISO/IEC TR 12860. It identifies a number of requirements impacting Next Generation Network (NGN) standardisation and concerning deployment of enterprise networks. The scope of this Technical Report is limited to calls from a user of an enterprise network to an authority, where the authority is represented by a SAP (PSAP or PEAP). This includes the special case where a PEAP acts as an enterprise user in making an emergency call to a PSAP. Authority to authority calls, authority to enterprise user calls and enterprise user to enterprise user calls within the context of an emergency are out of scope, with the exception of return calls and verification calls as follow-up to an emergency call from the user to an authority. This Technical Report focuses on emergency calls within a SIP-based NGCN using geographic location information to indicate the whereabouts of the caller. Emergency calls can originate from devices connected to the NGCN via various access technologies, e.g., SIP over fixed or wireless LAN (Local Area Network), TDM (Time Division Multiplex) networks, DECT (Digital Enhanced Cordless Telephone) networks, PMR (Private Mobile Radio) networks, PLMN (Public Land Mobile Network), etc. SAPs are assumed to be reachable either directly using SIP or via a gateway to some legacy technology (e.g., TDM). Furthermore, SAPs are assumed to be reachable either directly from the NGCN or via a public network accessed from the NGCN using SIP. In the latter case, the NGCN might identify the SAP and instruct the public network to route to the SAP, or alternatively the NGCN might leave the public network to identify the SAP, based on the location of the caller. In all cases the NGCN is assumed to deliver the location of the caller to the SAP, gateway or public network in order to provide appropriate information to the call taker at the SAP. The handling of incoming emergency calls at a SAP, even when the SAP is provided within an NGCN, is outside the scope of this Technical Report. This includes the case where a PSAP is provided within an NGCN and hence the NGCN can receive emergency calls from public networks. This also includes the case where a PEAP is provided within an NGCN and can receive emergency calls from other enterprise networks or other parts of the same NGCN. Different territories have different regulations impacting emergency calls, together with national or regional standards in support of these regulations. This Technical Report takes a general approach, which should be largely applicable to any territory. However, detailed differences might apply in some territories, e.g., country- or region-specific dial strings used to identify emergency calls.
